A teachers' union looks set to reignite the row over the boycott of Israel, which divided university lecturers last year and triggered an international storm.

The National Union of Teachers (NUT) is due to discuss a motion at its Easter conference that takes a pro-Palestinian stance on the occupation. It calls on its union to buy educational material produced by the Palestine Solidarity Campaign for use by students in schools.

The motion, which marks the 60th anniversary of the "unresolved injustice" of the "banishment of 750,000 Palestinians from their homelands", says that the campaign material "promotes an understanding of the history of this most protracted dispute in the Middle East".

It also wants the union to fund the publication of curriculum learning materials around peace and militarisation.

The motion goes on to urge members to stop promoting in schools career opportunities in the armed forces and to support any teachers who face "victimisation or other professional difficulties" in implementing the policy.

The motion, which comes from NUT members in Croydon, south London, is due to be debated at the conference in Manchester, which starts next Friday. It could trigger the same divisions in the union that split the University and College Union (UCU) last year.

Last May, the UCU provoked global condemnation after its national conference decided to take steps towards a vote on introducing an academic boycott of Israeli universities.

The ensuing row dragged on for four months and involved academics from across the world - especially in the US and Israel - sparking criticism from Jewish leaders, university vice-chancellors and the government.

In September last year the union cancelled the schedule of regional meetings organised for members to discuss the "moral implications " of existing links with Israel", which had included invitations to speakers from Palestinian trade unions living under Israeli occupation who had originally urged the union protest.

The union's U-turn followed advice from its lawyers that a boycott call ran the risk of infringing discrimination legislation and was also considered to be outside the aims and objects of the union.
